QUESTION: 132

Consider the following pseudo code:

1 Begin
2 Read Time
3 If Time < 12 Then
4 Print(Time, "am")
5 Endif
6 If Time > 12 Then
7 Print(Time 12, "pm")
8 Endif
9 If Time = 12 Then
10 Print (Time, "noon")
11 Endif
12 End

If the test cases Time = 11 and Time = 15 were input, what level of decision coverage would be achieved?

100% or 6/6
50% or 3/6
67% or 4/6
83% or 5/6

Answer(s): D

Explanation:

Test case 1 exercises the decision outcomes True, False, False
Test case 2 exercises the decision outcomes False, True, False
This leaves the True outcome of decision 3 not exercised.
Of the 6 possible decision outcomes, 5 have been exercised, so the decision coverage is 5/6 (about 83%).
